No it really isn't dielectric losses.
It's capacitive loading.
Exactly.
But the power isn't lost *in* the dielectric, its lost in driving the
current down the wires *to* the dielectric.
There is a niggling, and mostly insignificant loss in that the insulation
isn't a *perfect* dielectric, but yes, the main losses are in the
conductors.
There is a small amount of energy taken to reverse the electric field.

I just said that.
